I'm getting a bit fed up with my netbook nowadays, as the keyboard becomes increasingly frustrating to type on, and I'm looking to get an Apple laptop again. My interest is the 12" Powerbook since I don't think Apple will be releasing a netbook anytime soon. I have no idea how much faster/slower the G4 would be (I'm hoping to get at least a 1.0 Ghz), but I imagine it would be at least comparable to the Atom. My worry is, however, the battery. I know that at launch these things lasted a good 5-7 hours (same as my Acer Aspire One which gets a good 6 hours) but after the battery replacement program and of course, old age, batteries can last anywhere between 15 minutes to only 2.5 hours. How are the third-party batteries that are out there for G4 powerbooks? Would purchasing one of those bring my battery life back up to that elated 5-6 hour line? I'm thinking I need at least 4 hours, like the current-gen MacBooks. Here are some local Toronto deals I'm observing: http://toronto.en.craigslist.ca/tor/sys/1030259099.html http://toronto.en.craigslist.ca/tor/sys/1028544548.html http://www.iupgradecanada.com/12-powerbook-g4-549/ Note that the iUpgrade is a local store, and thus I'd pay taxes, shelling out closer to $650 CAD. Any advice? What's the best deal of those three? None of them really give any ballpark battery life figures, which I'm worried about, so figure another $80-100 for a new battery? Also I imagine 512 MB of RAM isn't nearly enough; DDR1 can be pricey nowadays, and I'd have to get a one gig stick... ouch!
